I was out walking Standley Lake's north shore (N end of Jefferson County) about 5pm yesterday 4/7, and was able to capture one of the adult BAEA's hauling in a duck (appears to be a Mallard). It was pretty far out, so the pics aren't as crispy as I'd like, but good enough to witness the effort put in to bring it to shore, rest for a couple minutes, then deliver it to the nest.
After talking with a ranger, she said it was dad bringing in the new eaglet's first meal.
